Review on 🚗 LEXXSON Android 10.1 Car Radio Stereo for Hyundai Sonata 2011-2013, 9" Capacitive Touch Screen HD Head Unit, Bluetooth USB Player, Split Screen GPS Navigation, 2G DDR3+32G by Jasmine Jimenez

Constant hum or hiss when turning on the car. I listen to it every time I'm not playing music and it's annoying. The factory radio didn't have this problem. I have a factory amp. I don't know if their canbus decoder is bad or their android autoblock. Lexxon tech support is terrible, they basically sent a photo of installing the unit in another model and told me to update the software. I think they don't understand English or their product very well. It's so frustrating. Revain sent me a replacement that had the same issues.
